Burn policy is:
No burnin'.

I will not be carrying anything on me- no bud, papers, lighters, or paraphenalia of any sort.

Use your head everyone- Cannabis is illegal in Massachusetts. The mounted police will no doubt be there as they are even when there ISN'T a festival on the Common. It's right at the State House and security is always tight.
I am going to show my support for the decrim cause, listen to some live music, and check out vendors.
I'll be doing my smoking elsewhere!

Oh... and the Yankees are in town... it's gon' be a ZOO. Go Sox.
